Abstract

The invention relates to analytical instrument-making engineering and can be used for analysing industrial gas and air emissions. The aim of said invention is to increase the sampling efficiency and to reduce, correspondingly the time of sampling. The inventive device for accumulating aerosols from gases comprises an atomiser connected to a gas pumping system, a needle, and a high-tension power supply. The atomiser is embodied in the form of a hollow cylinder provided with a dosing hole which is arranged in the central part of a lateral surface thereof. The gas pumping system comprises a dosing hole of the atomiser with a needle arranged therein. Said needle is provided with a means for moving it in relation to the atomiser. An orthogonal system used for introducing the gas flow through the dosing hole of the atomiser makes it possible to essentially increase (by 6 times) a pumping speed and correspondingly to reduce the time of a sample accumulation.
